图像垂直验证码的可用性及展望

Availability and Prospect of Image Vertical Verification Code

验证码是一种广泛应用于互联网领域的安全技术。笔者着重讨论一种基于图像方向识别的验证方式——图像垂直验证。该方式通过利用自动定位检测系统、社会反馈机制等技术手段,在提高可识别度、不影响准确率的前提下,大大提升了验证码的防破解能力。图像垂直验证技术的优势在于拥有海量的图像素材,不需要进行文本输入,与传统的文本识别验证方式相比,有利于快速通过验证,使用户获得更好的体验。

Verification code is a kind of security technology widely used in the field of Internet.This paper focuses on a verification method based on image direction recognition-image vertical verification.By using the technology of automatic location detection system,social feedback mechanism and so on,this method greatly improves the anti cracking ability of the verification code on the premise of improving the recognizability and not affecting the accuracy.The advantage of image vertical verification technology is that it has a large number of image materials and does not need text input.Compared with the traditional text recognition verification method,it is conducive to pass the verification quic kly and make users get a better experience.
